By factory default J1 is set open. If this board is the last board on the RS-485 bus,
install jumper J1 across both pins (closed). Closing J1 provides the bus termination
required.
Wiring
This section presents information on alarm contact wiring and control output wiring.
Alarm Contact Wiring
Inputs 0 to 15 may be configured to use normally open or normally closed contacts
and non-supervised or supervised (with standard ±1 tolerance 1K ohm). All 16 inputs
can be configured to monitor general-purpose alarm sensors or can be used as control
inputs.
Additional inputs TMP and PFL are typically used for monitoring cabinet tamper and
power failure respectively. These two inputs are not supervised and are not accessible
when the board is rack-mounted. These inputs are used when this board is mounted
remotely and cannot take advantage of the tamper and power fail detect inputs on the
controller board. If these inputs are not used, install a short piece of wire at the input to
indicate safe condition.
Input configuration including sensitivity and hold time is set via host software.
Control Output Wiring
Two form-C relay contacts are provided for controlling other devices. Each may be
assigned to a general-purpose output. They are configurable as standard (energize to
activate) or fail-safe (de-energize to activate) by the host software.
The energized or ON time of each relay can be configured using pulse control for
single or repeating pulses via host software. The energized or ON time of a single
pulse can be extended up to 24 hours. For repeating pulses, the on/off time can be
defined in 0.1 second increments and be repeated up to 255 times.
Relays 0 and 1 are rated for dry contact signal or load switching. While they are sized
to handle typical loads, load switching can cause abnormal contact wear and
premature contact failure. Switching of inductive loads (e.g., strikes) also causes EMI
(electromagnetic interference) which may interfere with normal operation of other
equipment. To minimize premature contact failure and to increase system reliability, a
contact protection circuit is highly recommended. The following circuit is suggested.
Locate the protection circuit as close to the load as possible (within 12 inches [30cm]);
the effectiveness of the circuit decreases as the distance from the load increases.
